Why is PETG rated this way to Hydrofluoric Acid?
PETG is not recommended for use with Hydrofluoric Acid. Significant degradation or failure is expected.
⚠️ When NOT to use PETG
Avoid using PETG with strong acids, alkalis, and most organic solvents. Better impact resistance than PET but lower chemical resistance.
